The $15 pendant necklaces contain dried, sterilized reindeer droppings -- sprayed with glitter -- on a beaded chain. They'll be available at the zoo's gift shop, or by mail for $20.
The ornaments are back, and 450 have already sold this season. About 1,500 are still available for $7.50, or $10 by mail.
Miller Park Zoological Society spokeswoman Susie Ohley admits it's a bit silly but estimates the zoo could make $16,500. The zoo lost $200,000 under city budget cuts this year.
